Impermanent Loss Calculator Guide: How LP Losses Work in DeFi
Financial Risk Warning:DeFi liquidity provision involves significant financial risk including total loss of deposited assets. Impermanent loss calculations are theoretical and do not account for smart contract risk, rug pulls, or protocol exploits. This guide is educational only — not investment advice. Never deposit more than you can afford to lose.
Quick Answer
- *Impermanent loss (IL) is the cost of providing liquidity versus simply holding your tokens.
- *A 2x price change in one token causes ~5.7% IL. A 5x change causes ~25.5% IL.
- *Over 50% of Uniswap v3 LPs lost money after accounting for IL vs fees earned (Bancor, 2023).
- *Stablecoin pairs and correlated assets minimize IL — stablecoin pools see under 0.1% IL annually.
What Is Impermanent Loss?
Impermanent loss happens when you deposit tokens into a DeFi liquidity pool and the price ratio between those tokens changes. The automated market maker (AMM) rebalances your position, leaving you with fewer of the token that went up and more of the token that went down.
The result: your pooled position is worth less than if you had simply held the tokens in your wallet. That difference is impermanent loss.
According to a 2023 Bancor research report, more than 50% of Uniswap v3 liquidity providers experienced net losses when comparing their LP returns against a simple hold strategy. The study analyzed over 17,000 LP positions across major trading pairs.
The Impermanent Loss Formula
For a standard 50/50 constant-product AMM (like Uniswap v2), the IL formula is:
IL = 2 × √(price_ratio) / (1 + price_ratio) – 1
Where price_ratio = new price / original price of the volatile token.
Impermanent Loss by Price Change
| Price Change | Price Ratio | Impermanent Loss | Loss on $10,000 Position |
|---|---|---|---|
| 1.25x (25% up) | 1.25 | 0.6% | $60 |
| 1.50x (50% up) | 1.50 | 2.0% | $200 |
| 2x (100% up) | 2.00 | 5.7% | $570 |
| 3x (200% up) | 3.00 | 13.4% | $1,340 |
| 5x (400% up) | 5.00 | 25.5% | $2,550 |
| 0.5x (50% down) | 0.50 | 5.7% | $570 |
| 0.2x (80% down) | 0.20 | 25.5% | $2,550 |
Notice that IL is symmetrical: a 2x increase and a 0.5x decrease both produce 5.7% loss. What matters is the magnitude of the ratio change, not the direction.
Real Example: ETH/USDC Pool
You deposit $10,000 into an ETH/USDC pool when ETH is $2,000. You contribute 2.5 ETH ($5,000) and 5,000 USDC ($5,000).
ETH rises to $4,000 (a 2x increase). If you had simply held your tokens, you'd have:
- 2.5 ETH × $4,000 = $10,000
- 5,000 USDC = $5,000
- Total if held: $15,000
But the AMM rebalanced your position. After the price change, you now hold approximately 1.77 ETH and 7,071 USDC:
- 1.77 ETH × $4,000 = $7,071
- 7,071 USDC = $7,071
- Total in pool: $14,142
Your impermanent loss is $15,000 – $14,142 = $858, or 5.7% of the held value. You still made money compared to your original $10,000 deposit, but you made $858 less than you would have by just holding.
When Do Trading Fees Offset IL?
Liquidity providers earn a share of every trade that passes through the pool. On Uniswap v2, LPs earn 0.3% of each trade's volume. Uniswap v3 offers flexible fee tiers: 0.01%, 0.05%, 0.3%, and 1%.
According to Chainalysis data from 2024, the top 25% of Uniswap v3 LPs earned 2–3x more in trading fees than they lost to impermanent loss. The bottom 25% consistently lost money. The difference came down to pool selection and position management.
| Pool Type | Typical Fee APR | Typical IL (Annual) | Net Result |
|---|---|---|---|
| Stablecoin pairs (USDC/USDT) | 2–8% | <0.1% | Profitable |
| Correlated pairs (stETH/ETH) | 1–5% | 0.1–1% | Usually profitable |
| Major pairs (ETH/USDC) | 10–50% | 5–20% | Varies widely |
| Small-cap pairs | 20–200% | 20–80%+ | Often negative |
DeFi Llama tracks over $45 billion in total value locked across AMMs as of early 2026. The highest-volume pools consistently generate enough fees to overcome IL, but selecting the right pool and fee tier is critical.
Concentrated Liquidity and IL (Uniswap v3)
Uniswap v3 introduced concentrated liquidity, letting LPs provide capital within a specific price range. This amplifies both trading fees and impermanent loss.
A position concentrated in a ±10% range earns roughly 10x more fees per dollar than a full-range position. But if the price moves outside your range, you hold 100% of the losing token and earn zero fees until the price returns.
Messari research found that concentrated positions within a ±5% range experienced 3–7x higher IL than full-range positions during the same period. Tight ranges are a double-edged sword.
Strategies to Minimize Impermanent Loss
1. Choose Correlated Pairs
Pools with assets that move together (stETH/ETH, WBTC/renBTC) have minimal price divergence and therefore minimal IL. Stablecoin pairs are the safest option for LP newcomers.
2. Provide Liquidity in High-Volume Pools
More trading volume means more fees. According to Dune Analytics dashboards, the ETH/USDC 0.3% pool on Uniswap v3 processes over $200 million in daily volume, generating substantial fee revenue for LPs.
3. Use Wider Price Ranges on v3
Wider ranges reduce fee concentration but also reduce IL exposure. A ±50% range is a reasonable starting point for volatile pairs.
4. Monitor and Rebalance
Check your position regularly. If the price moves significantly, you may want to withdraw and re-enter at a new range rather than letting IL compound.
5. Consider IL Protection Protocols
Some DeFi protocols offer IL protection. Bancor v2.1 pioneered single-sided liquidity with IL protection that vests over 100 days. Other protocols use options or insurance mechanisms to hedge LP positions.
Impermanent Loss vs Realized Loss
The word “impermanent” is misleading. IL only disappears if the price ratio returns to exactly where it was when you deposited. In practice, this rarely happens — especially with volatile assets.
A CoinGecko analysis of the top 100 DeFi tokens found that 78% experienced price changes exceeding 2x within a 12-month period. For most LP positions held longer than a few months, the loss becomes permanent upon withdrawal.

What is impermanent loss in DeFi?
Impermanent loss is the difference between holding tokens in a liquidity pool versus simply holding them in your wallet. It occurs when the price ratio of pooled tokens changes from the ratio at deposit. According to Bancor research, over 50% of Uniswap v3 liquidity providers experienced net losses in 2023 after accounting for impermanent loss versus fees earned.
How much impermanent loss occurs with a 2x price change?
If one token doubles in price relative to the other (a 2x price ratio change), impermanent loss is approximately 5.7%. For a $10,000 LP position, that means your pool share is worth about $570 less than if you had simply held the tokens. At a 5x price change, IL reaches 25.5%.
Can trading fees offset impermanent loss?
Yes, but it depends on the pool. High-volume pools like ETH/USDC on Uniswap can generate 10–50% APR in fees. If the fee APR exceeds the IL percentage over your holding period, you profit. Chainalysis data shows that top-decile Uniswap v3 LPs earn 2–3x more in fees than they lose to IL, while bottom-decile LPs lose money consistently.
Is impermanent loss permanent?
Impermanent loss is only realized when you withdraw from the pool. If the token price ratio returns to what it was when you deposited, the IL drops back to zero. However, if you withdraw while prices have diverged, the loss becomes permanent. The name “impermanent” reflects this reversibility, though in practice many LPs withdraw at a loss.
Which liquidity pools have the lowest impermanent loss?
Stablecoin pairs (USDC/USDT, DAI/USDC) have near-zero impermanent loss because their prices barely diverge. Correlated asset pairs like stETH/ETH or WBTC/BTC also minimize IL. According to DeFi Llama data, stablecoin pools typically see IL under 0.1% annually while still earning 2–8% in fees.
